Downloading
Operation Code
from a File Server
Automatic Operation Code Upgrade can automatically download an operation
code file when a file newer than the currently installed one is discovered on the file
server. After the file is transferred from the server and successfully written to the file
system, it is automatically set as the startup file, and the switch is rebooted.
Usage Guidelines
◆ If this feature is enabled, the switch searches the defined URL once during the
bootup sequence.
◆ FTP (port 21) and TFTP (port 69) are both supported. Note that the TCP/UDP
port bindings cannot be modified to support servers listening on non-standard
ports.
◆ The host portion of the upgrade file location URL must be a valid IPv4 IP
address. DNS host names are not recognized. Valid IP addresses consist of four
numbers, 0 to 255, separated by periods.
◆ The path to the directory must also be defined. If the file is stored in the root
directory for the FTP/TFTP service, then use the “/” to indicate this (e.g.,
ftp://192.168.0.1/).
◆ The file name must not be included in the upgrade file location URL. The file
name of the code stored on the remote server must be ECS5520.bix (using
lower case letters as indicated).
◆ The FTP connection is made with PASV mode enabled. PASV mode is needed to
traverse some fire walls, even if FTP traffic is not blocked. PASV mode cannot be
disabled.
◆ The switch-based search function is case-insensitive in that it will accept a file
name in upper or lower case (i.e., the switch will accept ECS5520.BIX from the
server even though ECS5520.bix was requested). However, keep in mind that
the file systems of many operating systems such as Unix and most Unix-like
systems (FreeBSD, NetBSD, OpenBSD, and most Linux distributions, etc.) are
case-sensitive, meaning that two files in the same directory, ecs5520.bix and
ECS5520.BIX are considered to be unique files. Thus, if the upgrade file is stored
as ECS5520.BIX (or even Ecs5520.bix) on a case-sensitive server, then the switch
(requesting ECS5520.BIX) will not be upgraded because the server does not
recognize the requested file name and the stored file name as being equal. A
